The Stratospheric Aerosol and Gas Experiment (SAGE-III) mission onboard the International Space Station (ISS) investigates the vertical distribution of ozone, trace gases and aerosols in Earth’s stratosphere and troposphere. These measurements will improve our understanding of ozone generation and destruction processes in the upper atmosphere, and how climate change is impacting those processes.

- The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument will monitor the condition of the ozone layer, which covers an area in the stratosphere 10 to 30 miles (16 to 48 kilometers) above Earth and protects the planet from the sun's harmful ultraviolet radiation. Its predecessors, SAGE I and SAGE II, which were mounted to satellites, helped scientists understand the causes and effects of the Antarctic ozone hole. The Montreal Protocol of 1987 led to an eventual ban on ozone-destroying gases and to the ozone layer's recovery; SAGE III, designed to operate for no less than three years, will allow scientists to continue monitoring its recovery.
